Conflict is found in all societies and takes a variety of forms. Any development intervention must deal with both the causes of conflict and its consequences. Additionally, some development interventions themselves generate conflict within societies. This online module addresses the multi-faceted nature of conflict: the complex causes, the diverse impacts conflicts have on development, and the range of actions that can help mitigate conflicts. By equipping development managers and others working on or in conflict situations with both analytical and practical tools, the module will help them to intervene in ways that are sensitive to these complex contexts.
